Abstract

The utility model relates to a vehicle networking system, including the driving computer, the computer of should driving a vehicle passes through the CAN bus communicates by letter with on -board control unit or execution unit, the CAN bus still is connected with, should expand the serial ports and be used for being connected with the external equipment who monitors bus data in real time, the utility model discloses directly drawing this utility model's extension serial ports on the CAN bus of vehicle, should expanding serial ports user oriented or hardware equipment provider, be convenient for and outside expansion equipment is connected, and convenient extension is peripheral applied. The extension serial ports not only can be used for monitoring in real time bus data, carries out failure diagnosis, can also detect other electronic equipment's working condition.

Description

A kind of car networked system

Technical field

The utility model relates to a kind of car networked system, particularly relates to one and is provided with extended serial port, is convenient to the car networked system directly connecting peripherals.

Background technology

At present, the serial ports that automobile is externally arranged generally only has an OBD serial ports (On-BoardDiagnostic, onboard diagnostic system), and under this serial ports is generally arranged on and puts down dish or other positions of console, for detecting the fault of vehicle.The interface of vehicle fault detection instrument connects this OBD serial ports, reads associated vehicle information.According to the prompting of diagnostic trouble code, maintenance personal can determine character and the trouble location of fault quickly and accurately.

But the OBD serial ports of car networking does not open to user, the fault diagnosis only for producer and maintenance center is used.Current car networked system does not also provide a kind of user oriented extended serial port.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of car networked system being provided with extended serial port, this serial ports is directly drawn from CAN, user oriented and producer open, and can realize real-time listening bus data, and convenient connection with external unit carries out Function Extension.

For solving the problems of the technologies described above, the utility model provides a kind of car networked system, comprise car running computer, this car running computer is communicated with vehicular control unit or performance element by CAN, it is characterized in that, described CAN is also connected with, and this extended serial port is used for being connected with the external unit of real-time listening bus data.

The beneficial effects of the utility model are: the extended serial port directly drawing this utility model on the CAN of vehicle, this extended serial port user oriented or hardware device providers, are convenient to be connected with the expansion equipment of outside, conveniently expand peripheral applications.Extended serial port can not only be used for real-time listening bus data, carries out fault diagnosis, can also detect the working condition of other electronic equipment.

On the basis of technique scheme, the utility model can also do following improvement.

Further, described extended serial port is also provided with power interface, for charging or the power supply of external unit.

Adopt the beneficial effect of further technical scheme: extended serial port also provides vehicle power interface, be convenient to power supply or the charging of peripheral electronic device, peripherals and portable equipment, include but not limited to mobile phone etc., directly can be inserted on this extended serial port and charge.

Further, described extended serial port is arranged on automobile center console.

Adopt the beneficial effect of further technical scheme: serial port setting is controlled on platform in the car, easy to use.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the stitch definition schematic diagram of extended serial port.

Embodiment

Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.

As shown in Figure 1, a kind of car networked system, comprising: car running computer, and this car running computer is communicated with vehicular control unit or performance element by CAN, and described CAN is also connected with, and this extended serial port is used for being connected with the external unit of real-time listening bus data.In vehicular control unit, engine control ECU, security control ECU etc. are communicated by high-speed CAN bus, airconditioning control ECU, Lighting control ECU and instrument control ECU etc. are communicated by low speed CAN, directly from high-speed CAN bus and low speed CAN, draw extended serial port, the extended serial port user oriented of drawing or hardware device providers, be convenient to be connected with the expansion equipment of outside, conveniently expand peripheral applications.Extended serial port can not only be used for real-time listening bus data, carries out fault diagnosis, can also detect the working condition of other electronic equipment.

As shown in Figure 2, be the definition of extended serial port, extended serial port has 1 to 10 to amount to 10 stitch, and stitch is defined as follows:

1, low speed CAN high level, P-CAN;

2, low speed CAN low level, P-CAN;

3, Vehicular accumulator cell high level;

4, retain;

5, high-speed CAN high level, B-CAN;

6, high-speed CAN low level, B-CAN;

7, retain;

8, Vehicular accumulator cell low level;

9, low speed CAN high level, L-CAN;

10, low speed CAN low level, L-CAN.

Wherein 4 and 7 stitch can carry out self-defined according to demand, reserve and are out convenient to later stage expansion use.

3 and 8 stitch are convenient to power supply or the charging of peripheral electronic device, and peripherals and portable equipment, include but not limited to mobile phone etc., directly can be inserted in charging or power supply on this extended serial port.

The above implementation step and method only have expressed a kind of embodiment of the present utility model, and the number of stitch and function can carry out arranging and defining according to demand.Foregoing description is comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.

Under the prerequisite not departing from the utility model inventional idea, the distortion done and improvement all should belong to the protection domain of the utility model patent.
